Time independent spatially periodic variations in the density and floating potential have been observed in the FM−1 spherator. On the exterior of the plasma Δn/n and Δφ/φ are found to be as much as 0.3. Experimental evidence indicates these variations are due to magnetic islands created by small field errors produced by the levitated ring. Calculations of the expected island size agree well with observations.
